1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Src homology 2-containing protein tyrosine phosphatase 2 (SHP2) is an attractive therapeutic target in oncology and immunology-related disorders. However, developing novel phosphatase inhibitors that combine high potency, selectivity, cellular permeability, and drug-like properties remains challenging. The discovery of an allosteric mode of inhibition for SHP2 was a breakthrough, enabling the development of selective inhibitors that stabilize the phosphatase in its inactive conformation. We identified 2H-indazoles as a privileged and underexplored scaffold. Using our recently described palladium-catalyzed domino reaction as a key synthetic step, 3-amino-2H-indazoles were efficiently accessed from readily available precursors, enabling rapid exploration of novel allosteric inhibitors of SHP2. This approach led to compound 17g, a potent and selective allosteric SHP2 inhibitor (SHP2
